我在 python 中很难做到这一点,我对这个主题的研究没有产生任何有用的东西。 使用请求和 M2Crypto 可以轻松获取和加载证书 import requests from M2Crypto import RSA, X509 mypem = requests.get('https://server.com/my_certificate.pem') cert = X509.load_cert_string(str(mypem.text), X509.FORMAT_PEM...
您可以使用 asn1crypto 以更好的方式执行此操作: from asn1crypto.x509 import Certificate with open("mycert.der", "rb") as f: cert = Certificate.load(f.read()) n = cert.public_key.native["public_key"]["modulus"] e = cert.public_key.native["public_key"]["public_exponent"] print("...
RSA用于加密数据,X509用于证书验证。在Python中,我们可以使用第三方库来实现这两种算法的应用。 RSA加密 RSA是一种非对称加密算法,其中公钥用于加密数据,私钥用于解密数据。下面是一个使用Python实现RSA加密和解密的示例代码: fromCrypto.PublicKeyimportRSAfromCrypto.CipherimportPKCS1_OAEP# 生成RSA密钥对key=RSA.genera...
